, According to this invention we provide ap-V` aratus for vulcamzin lengths or sheets ofrubber or of rubberized material comprising a vulcanlzing chamber formed between spaced shells together with means for supporting and sealing the material to be vulcan-v ized within the chamber and mechanism for Y moving the supporting and sealingmeans so Y as to be rotatable externally of the chamber.

The drum is preferably provided with central shaft, the drum and shaft being supported in a carriage having rollers to guide the axial movement from thek internal or vulcanizing position to the externalor winding v on and off position, the drum or` carriage being eitheror bothaxially moved or rotated by manual or power operated means such as a double action hydraulic cylinder and piston connected to the carriage.

In order that our invention may be more easily understood and readily carriedfinto effect, the saine will now be described with reference to the accompanying drawing,

Y` which is a part sectional side view ofthe apthe outer endV by a permanent fluid proof paratus. i

Thek vulcanizing chamber lis formed between two concentric shells 2 and: 3 sealed at joint 5.

The door 9is formed at 14C to support a cylindrical surface 15 within and between the Ilshells 2 and l3 forming the vulcanizing cham- The cylindrical surface 15 may beformed i-of rods or*of-openworkformation to lreduce weight and to' allow'free' action ofthe fluid Vupon the material wound upon it.

V2. An apparatus Jfor vulcanizing lengths or sheets of rubber or rubberized material 5 comprising` inner and outer shells spaced to form an annular vulcanizing chamber, a fixed closure for one end of said chamber, a mov- Y able closure for `the opposite end thereof and supporting means for the material carried by said movableclosure and power means for moving` the latter. i Y Y 3. An apparatus for vuleanizing lengths or sheets of rubber or rubberized material comprising inner and outer shells spaced to form an annular vulcanizing chamber, a fixed elosure for one end of said chamber, a movable Closure for the opposite end thereof, means for 'rotatably supporting said closure and a material support carried by said closure.
